Answer:</h3>
<h3>
Step-by-step explanation:</h3>
If the trapezoid is isosceles, angles A and C are supplementary, so ...
... (4x+4) +(7x+11) = 180
... 11x +15 = 180 . . . . . . collect terms
... 11x = 165 . . . . . . . . . subtract 15
... x = 15 . . . . . . . . . . . . divide by the coefficient of x
And angles C and E are congruent.
... 4·15 +4 = 21y +1
... 63 = 21y . . . . . subtract 1
... 3 = y . . . . . . . . divide by the coefficient of y
Answer:
-22
Step-by-step explanation:
<span>DE = EB
DE = p + 15
I would help you farther but I don't know what p equals. If you know then add that number with 15 and you have your answer.</span><span />
The answer you're looking for is s=6.
by substitution you'd get 6.
